Previously we would write to header before writing our chunk data, which opens a window for corruption (or we would overwrite entirely). Now the saving process has been changed to follow this chain of events: 1. We always allocate a new space to write so we do not potentially overwrite and corrupt the current data 2. Write the chunk data first (the order of the fields in the chunk data isn't relevant though) 3. Flush to disk 4. Write to the region header last 5. Flush to disk 6. Then we free the previous space allocated With this chain of events it is impossible for a chunk write to corrupt a region file, unless the operating system has lied and we have NOT flushed to disk. However server administrators are still recommended to continue performing regular backups. Note that when Mojang finally decides to change their region format to deal with oversized chunks this patch must be changed to deal with whatever system they decide to impose. We also make use of two flushes to disk per chunk save (to ensure ordering and ensure data has gone to disk), so this will negatively affect save performance. |
